ProtonVPN is a virtual private network service developed by Proton AG, the Swiss company best known for Proton Mail. Designed with privacy and security as primary goals, ProtonVPN aims to give users control over their online data while offering usable performance for everyday tasks such as web browsing, streaming, and P2P file sharing. Privacy and jurisdiction One of ProtonVPN’s standout features is its Swiss jurisdiction. Switzerland has strong privacy laws and is outside EU and US surveillance alliances, which makes it an attractive home base for a privacy-focused service. ProtonVPN also follows a strict no-logs policy: it does not record users’ activity or connection logs that could be used to trace online behavior back to an individual. Security and technology ProtonVPN uses modern VPN protocols including WireGuard, OpenVPN, and IKEv2. WireGuard is often the fastest and is widely recommended for most users due to its balance of performance and strong cryptography. ProtonVPN implements strong encryption standards and offers additional protections such as DNS leak protection and a kill switch that blocks internet access if the VPN connection drops. Secure Core and advanced features A signature offering is Secure Core, which routes traffic through multiple, hardened servers located in privacy-friendly countries before it exits to the public internet. This multi-hop design adds protection against certain types of network-level attacks. ProtonVPN also provides features like split tunneling, specialized P2P servers for torrenting, and dedicated streaming servers that help access region-restricted content. Free plan and paid tiers ProtonVPN provides a free tier with limited server options and medium speeds, which is notable because it doesn’t impose data caps like many free VPNs. Paid plans unlock all servers, higher speeds, Secure Core, simultaneous connections, and advanced features. Pricing is competitive with other premium VPNs, and Proton often bundles VPN with other Proton services for added value. Usability and transparency ProtonVPN offers apps for Windows, macOS, Linux, iOS, and Android, plus manual configuration options for routers. The apps are open source, allowing security researchers to audit the code, and the company publishes transparency reports and independent security audits. Considerations No VPN can guarantee absolute anonymity — users should combine a VPN with good personal security practices. Performance can vary by server load and location; testing a trial or the free plan helps determine whether speeds meet your needs. Geo-unblocking success (for streaming platforms) can change over time as services update their defenses. Conclusion ProtonVPN is a strong choice for privacy-conscious users who want a transparent, well-audited VPN backed by a company with a privacy-first reputation. Its combination of secure protocols, Swiss jurisdiction, Secure Core multi-hop routing, and a usable free tier makes it worth considering whether your priority is privacy, security, or accessing region-restricted content.#1#

: Navigating and Ranking Connections Beyond the First Degree Keywords nthlink, link-ranking, graph discovery, nth-degree connections, recommendation, graph analytics, trust propagation, personalization Description nthlink is a framework for discovering and ranking nth-degree connections in graphs and networks, improving discovery, recommendations, and trust-aware navigation across web, social, and enterprise systems. Content Modern networks—social graphs, knowledge bases, citation networks, and the web—are defined not just by direct links but by chains of relationships that span multiple hops. nthlink is a conceptual framework and set of techniques for identifying, scoring, and surfacing useful nth-degree links (connections via n intermediate steps) so systems can provide richer discovery and recommendation experiences while respecting relevance and trust. What nthlink does At its core, nthlink evaluates paths of length n between nodes and produces a ranked set of candidate connections. Instead of treating distant nodes as noise, nthlink measures relevance using path quality, context, and decay. The result is a curated view of “second-, third-, or nth-degree” relationships that are often valuable but hard to find with simple adjacency queries. How it works Key components of an nthlink system: - Path sampling and enumeration: Efficiently explore candidate paths up to a bounded n using breadth-limited search, random walks, or Monte Carlo sampling. - Edge weighting and decay: Assign weights to edges (e.g., interaction frequency, semantic similarity) and apply a decay factor per hop so longer chains contribute less unless supported by strong signals. - Path scoring and aggregation: Score individual paths by combining edge weights, path diversity (different types of relations), and recency; aggregate multiple paths connecting the same nodes to compute a final nthlink score. - Contextual filtering: Incorporate user context, query intent, or domain constraints to prioritize connections relevant to the current task. - Trust and provenance: Surface provenance information and trust metrics (source reputation, corroboration) so users can assess the reliability of a distant connection. Applications - Social discovery: Suggest meaningful second- or third-degree contacts for networking or introductions. - Recommendations: Find products, articles, or collaborators that are connected indirectly through shared interests or behaviors. - Enterprise knowledge: Reveal latent relationships across documents, teams, and projects to accelerate problem solving. - Fraud and security: Detect suspicious collusion by tracing multi-hop transaction chains that wouldn’t be obvious from direct links alone. Benefits and challenges nthlink enables serendipitous discovery, increases coverage beyond immediate neighbors, and provides nuanced signals for personalization. Challenges include scalability (combinatorial path growth), signal noise from weak links, privacy concerns when surfacing hidden relationships, and the need for explainability so users trust recommendations. Implementation tips Limit search depth, precompute popular paths, use graph embeddings to approximate distant similarity, and apply strict provenance and privacy controls. Start with domain-specific heuristics and evolve toward hybrid models combining analytics and learned ranking. Conclusion nthlink transforms how systems reason about connections by treating multi-hop relationships as first-class signals. With careful weighting, context, and governance, nthlink can unlock valuable insight across social, web, and enterprise graphs while maintaining performance and tr

PN: Secure, Private, and Transparent VPN Service Keywords ProtonVPN, VPN, Secure Core, WireGuard, no-logs, Swiss VPN, ProtonMail, VPN for privacy, VPN audit, VPN free plan Description ProtonVPN offers a privacy-first VPN with strong encryption, Secure Core multi-hop, open-source apps, and a free tier — ideal for users seeking transparent, Swiss-based protection online. Content In an era when online privacy is increasingly under threat, ProtonVPN positions itself as a privacy-first virtual private network built on principles of transparency, strong encryption, and independent oversight. Founded by the same team behind ProtonMail and headquartered in Switzerland, ProtonVPN benefits from the country’s robust privacy laws and a company ethos that emphasizes user rights. Security and privacy are the core pillars of ProtonVPN’s offering. The service uses industry-standard encryption (AES-256) and supports modern VPN protocols including WireGuard, OpenVPN, and IKEv2. ProtonVPN apps are open source, allowing security researchers and users to inspect the code; the company has also subject its apps to independent audits, reinforcing trust in their claims. A strict no-logs policy means ProtonVPN does not store connection logs that could be used to identify users. One of ProtonVPN’s standout features is Secure Core, a multi-hop architecture that routes traffic through a chain of hardened servers in privacy-friendly jurisdictions before exiting to the internet. This reduces the risk of traffic correlation attacks and adds an extra layer of anonymity, particularly valuable for users in high-risk environments or those who require enhanced privacy. ProtonVPN also offers Tor over VPN integration, enabling seamless access to the Tor network without running a separate Tor client. Feature set and usability are well-rounded. ProtonVPN includes a kill switch to prevent data leaks if the VPN connection drops, DNS leak protection, and split tunneling on supported platforms. P2P-friendly servers, streaming-optimized servers, and high-bandwidth options make ProtonVPN suitable for file sharing and media consumption. The apps are designed with clarity in mind, making it accessible for beginners while still offering advanced options for experienced users. Performance and coverage have improved with an expanding server network. ProtonVPN maintains servers in many countries worldwide, and adoption of WireGuard has boosted typical throughput while keeping overhead low. As with any VPN, real-world speeds vary by server choice, location, and network conditions, but ProtonVPN strikes a good balance between security and performance. ProtonVPN provides a free tier that’s useful for casual users who want basic encrypted browsing without cost. Paid plans unlock higher speeds, Secure Core, access to all server locations, and support for more simultaneous connections. Pricing aims to be competitive and is often bundled with ProtonMail for those who want a privacy suite. No product is perfect: advanced privacy features can add complexity, and the best speeds are reserved for paid subscribers. Nonetheless, for users prioritizing transparency, auditing, and a strong privacy stance — backed by Swiss jurisdiction — ProtonVPN is a compelling choice. Whether you want a reliable free option or a full-featured paid plan with multi-hop and streaming support, ProtonVPN remains one of the most reputable players in the consum
